UltraMobilePC
IMPORTANT! To protect the hard drive, wait at least 5 seconds after turning OFF
your UltraMobilePC before turning it back ON.
IMPORTANT! Do not use emergency shutdown while data is being written; doing
so can result in loss or destruction of your data.
WARNING! Do not leave the battery pack discharged. The battery pack will discharge
over time. If not using a battery pack, it must continued to be charged every three
months to extend recovery capacity or else it may fail to charge in the future.
NOTE: The battery stops charging if the temperature is too high or the battery voltage
is too high. BIOS provides a smart battery refreshing function. If the battery calibra-
tion process fails, stop charging and contact an authorized service center.
Charging the Battery Pack
Before you use your UltraMobilePC on the road, you will have to charge the battery pack.
The battery pack begins to charge as soon as the UltraMobilePC is connected to external
power using the power adapter. Fully charge the battery pack before using it for the first time.
A new battery pack must completely charge before the UltraMobilePC is disconnected from
external power. It takes a few hours to fully charge the battery when the UltraMobilePC is
turned OFF and may take twice the time when the UltraMobilePC is turned ON. The battery
status indicator on the UltraMobilePC turns OFF when the battery pack is charged.
Power Options
The power switch turns ON and OFF the UltraMobilePC or putting the UltraMobilePC
into sleep or hibernation modes. Actual behavior of the power switch can be customized in
Windows Control Panel “Power Options.”
For other options, such as “Switch User, Restart, Sleep, or Shut
Down,” click the arrowhead next to the lock icon.
Restarting or Rebooting
After making changes to your operating system, you may be
prompted to restart the system. Some installation processes
will provide a dialog box to allow restart. To restart the system
manually, choose Restart.
Emergency Shutdown
In case your system cannot properly turn OFF or restart, hold the power button over 4
seconds.
